Research On Light Field Imaging Technology Based On Aperture Modulation

In the aftereffect process of the impact target,the effective acquisition of the spatial position information of the target of the penetration target is a key issue in the detection and processing of the scene information of the impact process.Due to the rapid transient change of the impact process,the traditional single-view imaging cannot effectively detect the target under occlusion.The multi-eye imaging system composed of two or more high-speed cameras has problems such as large system and high hardware cost.In this paper,the problem of spatial location information acquisition of specific targets in the target group of impact process is proposed.Multi-view imaging method using aperture modulation is proposed to obtain multi-view information for the penetration process.In this paper,the multi-view imaging system based on aperture coding is designed and constructed by the effective viewing angle,sub-view field of view,inter-view parallax and spatial resolution.The 3DSMAX software is used to simulate the impact target process to construct a “virtual” multi-views.The system aims to obtain multi-view image information of the penetration process,and studies the influence of illumination mode on the acquisition of the information of the penetration scene.Aiming at the problems of traditional synthetic aperture imaging,such as limited bluffing of foreground occlusion fragments and poor reconstruction quality of penetrating object,this paper proposes a synthetic aperture algorithm based on the target of interest.According to the characteristics of the object and the fragmentation information in the impact scene,a specific target extraction algorithm is proposed,which combines the synthetic aperture imaging algorithm to remove the non-target ray to solve the problem of the target of the penetration object in the occlusion situation in the impact scene.The proposed algorithm is validated by the simulation data and the actual collected data.The results show that the proposed algorithm can effectively distinguish the fragmentation information from the object of the penetration target in the impact scene,and obtain a better reconstructed image of the target.
